Figure Lengend Snippet: The anti-IL-17A antibody clone eBio17CK15A5 inhibits the biological activity of IL- 17A in vitro . (A,B) The rat renal tubular cell line (NRK52E cells) was stimulated with IL-17A or TNFα+IL-17A in absence or presence of neutralizing IL-17A antibody (n = 4 independent experiments). Unstimulated cells served as control. The gene expression of the IL-17A target genes CCL20 and CXCL1 served as readout. Stimulation with IL-17A induced the gene expression of CCL20 and CXCL1 already after 24 h. Co-stimulation with TNFα further increased CCL20 and CXCL1 transcripts. The presence of IL-17A antibody led in all cases to a reduction of CCL20 and CXCL1 transcripts confirming the inhibitory activity of the antibody.
